IAS 37.14 — A provision shall be recognised when: (a) an entity has a present obligation from a past event; (b) it is probable that an outflow will be required; (c) a reliable estimate can be made.

IAS 37.36 — The amount recognised shall be the best estimate of the expenditure required to settle the present obligation at the end of the reporting period.

IAS 37.39 — Where there is a large population of items, the obligation is estimated by weighting all possible outcomes by their associated probabilities (expected value).

IAS 37.45 — Where the effect of the time value of money is material, the amount of a provision shall be the present value of the expenditures expected to settle the obligation.

IAS 37.72 — A constructive obligation to restructure arises only when an entity has a detailed formal plan and has raised a valid expectation in those affected.

IAS 37 Provisions in Real Estate

Real estate and property companies carry provision portfolios dominated by physical asset obligations: lease reinstatement costs, environmental remediation for contaminated sites, construction defect liabilities, and demolition provisions. Lease reinstatement provisions are almost universal for property companies that lease and modify commercial spaces — the obligation to restore premises to their original condition at lease end meets all three IAS 37 recognition criteria at the point the modifications are made, not at lease end. Environmental remediation provisions are significant for developers working with brownfield sites, where contamination from previous industrial use creates legal obligations under environmental legislation. Construction defect provisions affect property developers during the defect liability period following project completion, typically 2-10 years depending on jurisdiction and contract terms.

Measurement Considerations for Real Estate

Lease reinstatement provisions should be measured at the best estimate of the cost to restore premises to the condition specified in the lease agreement. This typically includes stripping out tenant improvements, removing fixtures and fittings, repairing any damage, and potentially reinstating original services configurations. The provision is recognised when the obligation arises — at the point the entity makes modifications to the premises, not at lease end. For properties with long remaining lease terms (5+ years), the provision must be discounted to present value using a pre-tax rate. The corresponding debit entry depends on the nature of the obligation: for new leases, it forms part of the right-of-use asset under IFRS 16; for modifications to existing properties, it may be capitalised as part of the fit-out cost. Construction defect provisions for developers with large portfolios should use the expected value method, weighting probable defect claims by their likelihood and cost based on historical defect data from completed projects.

Regulatory Context and Audit Considerations

Environmental remediation obligations for real estate are governed by national environmental legislation (e.g., Environmental Liability Directive 2004/35/EC in the EU, CERCLA/Superfund in the US). Due diligence on acquisitions should identify contamination risks that will create IAS 37 obligations. The provision should be recognised when the contamination is identified and a legal or constructive obligation to remediate exists — this is often at the point of acquisition, with the cost forming part of the property's carrying amount. Onerous lease provisions for vacant properties require careful analysis: if a property is vacant but the entity has an unavoidable lease obligation that exceeds any sublease income, the net cost represents an onerous contract under IAS 37.66. The May 2020 amendment to IAS 37 is relevant here: the cost of fulfilling includes not just incremental costs but also an allocation of directly related costs.

Common Provision Types in Real Estate

lease reinstatement

Obligation to restore leased premises to original condition — common for property developers who lease and modify commercial spaces

Typical: €50K-€2M per property Timeline: Remaining lease term Method: Best Estimate
environmental

Contaminated land remediation — brownfield sites, asbestos removal, industrial legacy contamination

Typical: €200K-€20M Timeline: 2-15 years Method: Best Estimate
construction defect

Developer liability for construction defects in completed properties — structural, waterproofing, fire safety

Typical: 1-5% of construction cost Timeline: 2-10 years (defect liability period) Method: Expected Value
onerous contract

Onerous lease provisions for vacant properties where rental income is below unavoidable costs

Typical: NPV of lease losses Timeline: Remaining lease term Method: Best Estimate
asset retirement

Demolition provisions for properties at end of life or required to be demolished under planning conditions

Typical: €100K-€5M Timeline: 5-30 years Method: Best Estimate

Worked Example: Meridian Property Development BV

Meridian holds a 15-year lease on a 3,000m² commercial property that was extensively modified for a tenant who has now vacated. The lease requires reinstatement to base-build specification at lease end (8 years remaining):

Nominal reinstatement cost: €420,000. Timing: 8 years to lease end. Discount rate: 3.5% (pre-tax rate reflecting time value and risk specific to the obligation). Present value = €420,000 / (1.035)^8 = €420,000 / 1.3168 = €318,916. The provision is recognised at €318,916 (PV). Each year, the discount unwinds: Year 1 interest = €318,916 × 3.5% = €11,162, increasing the provision to €330,078.

Provision Amount
€318.916
Regulatory Context: Environmental Liability Directive (2004/35/EC) creates legal obligations for land contamination remediation across the EU. National building codes create defect liability obligations for property developers. IFRS 16 and IAS 37 interact on lease reinstatement — the provision affects the right-of-use asset measurement.

Frequently Asked Questions — Real Estate

When should a lease reinstatement provision be recognised for real estate?
The provision is recognised when the obligation arises — typically when the entity modifies the leased premises, not at lease end. At the point of making alterations that must be reversed, the entity has a present obligation (from the lease terms), outflow is probable (the lease requires reinstatement), and a reliable estimate can be made (based on restoration cost estimates). If the remaining lease term exceeds one year, the provision should be discounted to present value.
How should onerous lease provisions be calculated for vacant properties?
An onerous lease provision is recognised when the unavoidable costs of meeting the lease obligation exceed the expected economic benefits. For a vacant property, this is typically the remaining lease payments less any sublease income. Following the May 2020 IAS 37 amendment, the cost of fulfilling includes both incremental costs and an allocation of directly related costs (e.g., property maintenance, insurance, rates). The provision equals the lower of the net cost of fulfilling the lease and the penalty for terminating it.
How does IFRS 16 interact with IAS 37 lease reinstatement provisions?
Under IFRS 16, the initial measurement of the right-of-use asset includes an estimate of costs to dismantle, remove, or restore the underlying asset as required by the lease terms. This means the reinstatement provision recognised under IAS 37 has a corresponding debit to the right-of-use asset, not to profit or loss. Changes in the provision estimate are adjusted against the ROU asset under IFRIC 1 principles. The provision and the ROU asset are separate but linked accounting entries.
How should construction defect provisions be measured for property developers?
Property developers should assess construction defect provisions using the expected value method if they have a portfolio of completed projects. Historical data on defect claims by type (structural, waterproofing, mechanical/electrical, fire safety) and severity provides the statistical basis. For individual large developments, specific assessment of known defects or claims is more appropriate. The defect liability period varies by jurisdiction and contract — typically 2-10 years from practical completion.
When does contaminated land require an IAS 37 environmental provision?
A provision is required when contamination is identified and a legal or constructive obligation to remediate exists. Legal obligations arise from environmental legislation (e.g., the Environmental Liability Directive in the EU). Constructive obligations can arise from published corporate environmental policies or established patterns of practice. The provision is measured at the best estimate of remediation cost, discounted to present value for long-term remediation programmes. Due diligence on property acquisitions should identify contamination as part of the provision assessment.
